euthanesia of feeders

hey there, i breed ASF's as feeders for my snakes, as i primarily keep ball pythons.

i live in canada, and it is impossible to get dry ice up here and nowhere in my town sells paintball supplies.

i have heard that using those cans of compressed air (for cleaning out computers/computer keyboards, etc) produce c02? is it safe to put feeders in a sealed container and release some of the compressed air into the chamber to euthanize? compressed air, i think called Dust Off is readily available at walmart, but i just haven't heard much on weather or not it's actually safe to use to euthanize feeders. i don't want my snake ingesting anything that will have illeffects later.

please advise on weather this is safe.

Google says that isn't CO2: http://www.sisweb.com/referenc/msds/dustoff.pdf

I vote for going onto the aquarium hobbiest forums and reading about how to set up a CO2 system for a freshwater planted tank. Usually they use a CO2 fire extinguisher as the source which is MUCH easier to find in Canada then dry ice :rofl:

Vineger and bakeing soda create CO2. Here is a link http://www.alysion.org/euthanasia/

Go to a local place that sells fountain pop in high volume, and ask them where they get their CO2 tanks filled.........

Any welding supply shops in your area? They could be able to hook you up with a small cyclinder of co2.
